Subject: [PATCH v2 0/4] drm/vc4: tests: Fix locking failures
Date: Thu, 03 Apr 2025 15:33:29 +0200 [thread overview]
Message-ID: <20250403-drm-vc4-kunit-failures-v2-0-e09195cc8840@kernel.org> (raw)
Hi,
This series deals with (lack of) EDEADLK handling in vc4 PV muxing
tests.
This was leading to failures with CONFIG_DEBUG_WW_MUTEX_SLOWPATH
enabled.
Maxime
